点击第一窗体的“开始”按钮，无法弹出第二个窗体。（vb语言）

Question

第一个窗体的代码：
Public Class Form1
Private Sub Label1_Click(sender As Object, e As EventArgs)

End Sub

Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles WellcomeTextbox.TextChanged, TextBox1.TextChanged

End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

End Sub

    Private Sub Button1_Click()
    Hide()
    Form2.Show()
End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

End Sub

End Class

第二个窗体代码：
Public Class Form2
Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load

End Sub

End Class

现在调试第一个窗体的代码，点击第一个窗体的“开始”按钮后，却无法弹出第二个窗体。

本人刚开始学习VB,也许问题很幼稚，请大侠不吝赐教！先谢过。
